Yes...
He got there in 2016. Their full-backs - he didn't buy them. He implemented a style that season and needed full-backs, so they went and bought full-backs, rather than try and improve 30+ year-olds Sagna and Clichy, they went and got Walker and Mendy.
Zinchenko was signed as a midfielder for a small fee as a teenager, Pep has transformed him into a left-back. Bloody hell, he turned Delph into a left-back.
Yes, City spent loads of money, but that doesn't guarantee you the succees they've had does it? Pep still has to put them all together, make them work. He turned Bernardo Silva from a diminutive playmaker to someone who is basically box-to-box. KDB has improved massively under him, look at how Foden has developed.
It's a really weird critique.
Everton have spent £500m in the past 5 seasons. Look at what a mess we are.
As for Grealish, he's an excellent player, sure he'll do well if he goes to City.
